12 1. SYSTEMAND METHOD FOR NEGOTATING A SHARED FLIGHT ITNERARY FIELD OF THE INVENTION This application claims the benefit of U.S. Provisional Application No. 61/105,658, filed on Oct. 15, The present invention relates generally to air charter brokerage operations regulated under 14 CFR 135 and 121 and more particularly, relates to a system and method whereby an air 10 charter brokerage's service enables users with similar or matching travel plans to find and contact each other to directly negotiate a shared flight itinerary, including departure and destination location as well as date and time. The invention is further disclosed as a system and method to enable said users 15 to directly book the shared itinerary via a website where said air charter brokerage service which will provide a charter aircraft. DESCRIPTION OF THE PRIOR ART Private air travel has many advantages over its commercial alternative. In the US, private aviation offers access to ten times as many airports as commercial airlines. According to current statistics, more than 90 percent of the US population 25 lives within 30 minutes of one of the more than 5,000 general aviation airports, compared to only 20 percent of the US population living within 30 minutes of the less than 500 airports serviced by commercial airlines. Especially for busi ness users the use of Smaller airfields and/or private aviation 30 facilities means more flexibility, shorter distances to the air port, shorter distances to clients, less crowding, more com fort, more privacy, and more productivity. However, a relative disadvantage of private air travel is the higher cost per seat, since private aircraft tend to have far fewer available seats 35 between which the cost of the trip may be shared. To address the relatively high cost of private air travel, different aircraft ownership and aircraft use models have been established. The basic approach to private air travel is full ownership and full control of the aircraft by a user (e.g., an 40 individual person, a business, etc.). However, full ownership also means liability for the full cost associated with the acqui sition, operation and maintenance of the aircraft, regardless of whether it is utilized for a trip or just sitting idle or whether only one or all available seats of the airplane are occupied. 45 To ease the financial burden associated with aircraft own ership, many owners prefer to only purchase a share in an airplane and thus divide the cost liability among all share owners. These arrangements are commonly referred to frac tional ownership. Fractional owners are typically liable for 50 their initial share of the purchase price, a monthly manage ment fee, an hourly fee per flight hour used by the fractional OW. Many users do not want to commit to full or fractional ownership of an aircraft, but still want to enjoy the advantages 55 of private aviation while having better control of the associ ated costs. For this type of user, so called on-demand charter Solutions are available. A user typically contacts one of the many available aircraft charter operators or charter aircraft brokers (collectively, air charter brokerage') and requests an 60 airplane for the desired flight itinerary, which includes infor mation about the number of travelers, the departure location, the departure date and time, and the arrival location. Thus, the user negotiates directly with the charter operator. The charter operator will then arrange for an aircraft to meet the desired 65 itinerary. Typically, users of chartered aircraft pay on a trip by trip, pay as you go basis. However, in addition to being 2O 2 charged for the actual flight time, the user may also be charged for empty return flights or repositioning of the air craft. In addition, the user must charter the entire plane and not only individual seats. The Federal Aviation Administration ( FAA) regulates on-demand charter and commuter operations in 14 CFR 135 and 121. On-demand charter operators and commuter opera tors require a specific certificate to conduct their operations under 14 CFR 135 and CFR defines commuter operations, in relevant part, as any scheduled operation conducted by any person operating certain types of aircraft... according to the published flight schedules. 14 CFR further defines scheduled operations as any common carriage passenger carrying operation for compensation or hire which offers in advance the departure location, departure time, and arrival location. Furthermore, any passenger-carrying operation that is conducted as a public charter operation under 14 CFR 380 (Public Charters) is not included under such scheduled operations. In other words, commuter operations are autho rized to conduct and offer to the public pre-existing, i.e., scheduled flights, whereby the flight parameters of departure location, departure time and arrival location are non-nego tiable. 14 CFR defines on-demand operations, in relevant part, as any passenger-carrying operations conducted as a public charter under 14 CFR 380 or any operations in which the departure time, departure location, and arrival location are specifically negotiated with the customer. In addition, 14 CFR defines charter flight, in relevant part, as a flight operated under a charter contract and as such charter flights do not include scheduled air transportation sold on an indi vidually ticketed or individually waybilled basis. In other words, on-demand charter operations are not authorized to conduct and offer to the public pre-existing, i.e., scheduled flights that are individually ticketed, but can only offer on demand services whereby the departure location, departure time and arrival location are specifically negotiated between the customer and the charter operation before the flight is scheduled. Unlike a scheduled flight, which will generally take place with or without a particular paying customer, an on-demand charter flight will not take place until negotiated between the customer and the air charter operator. Therefore, current attempts in the charter industry to sell open individual seats on scheduled flights or individual seats on empty 'scheduled one-way flights are arguably in violation with FAA rules and regulations. Still, there is a need to conduct operation of on-demand charter flights which minimizes open seats and empty flights on charter aircraft, which are in compliance with FAA rules and regulations. The prior art of matching travelers proposed travel plans in order to efficiently consolidate itineraries to share the cost of travel is plentiful. U.S. Pat. No. 7,080,019, hereby incorpo rated by reference, teaches a method which enables travelers to discover other travelers with similar and compatible travel plans, for purposes of contacting them and negotiating shared travel agreements. United States Publication Number 2004/ , hereby incorporated by reference, teaches a system and method, which facilitates the consolidation of users, automatically via an interactive media, so as to share a desired commodity with the intended purpose of reducing the cost-of-use to each user. More specifically, individual passengers wanting to travel on a private aircraft, from a departure of their choice, to a desti nation of their choice, at a time and date of their choice, can share the costs of renting said aircraft among themselves.

13 3 United States Publication Number 2006/ , hereby incorporated by reference, teaches a system whereby a user enters a trip, seeking an individual seat on a charter aircraft. Available charter operators and aircraft are then selected from a database using scheduling and pricing algorithms to match the passenger's request to existing flights and newly created flights. However, there is currently no system which provides users of on-demand air charter operations with an FAA compliant completely integrated system for itinerary consolidation. It would therefore be desirable if users could share the cost of a private charter aircraft by accessing an online meeting place which enables users to directly negotiate the creation of shared flight itineraries before the flight is scheduled and the aircraft is chartered. In addition, the users who collectively negotiated and created a shared flight itinerary would then be able to directly schedule the shared flight and collectively charter an aircraft using the services of a charter aircraft brokerage service. OBJECTS OF THE INVENTION Accordingly, it is an object of this invention to provide a system and method for enabling users to propose their desired flight itineraries to an open forum of other users. It is another object of this invention to provide a system and method for enabling users to search for open proposed flight itineraries of other users that match or are similar to the searching user's travel plans, in order to find and directly negotiate with each other a common shared flight itinerary that includes departure and destination location as well as date and time. It is yet another object of this invention to provide a system and method for enabling users to invite one another to directly book a common shared flight itinerary, on a per seat, pro rata basis, whereby an air charter brokerage service will provide a charter aircraft for the shared flight itinerary. SUMMARY OF THE INVENTION Accordingly it is an advantage of the present invention to enable users to search for open proposed flight itineraries of other users that match or are similar to the searching user's travel plans, in order to find and directly negotiate with each other a common shared flight itinerary. It is a further advantage of the present invention to enable users to invite one another to directly book a common shared flight itinerary, on a per seat, pro rata basis, whereby an air charter brokerage service will provide an charter aircraft for the shared flight itinerary. To achieve the foregoing and other advantages, and in accordance with one aspect of the present invention, a method for allowing searching users and proposing users to directly negotiate a shared flight itinerary for an on-demand charter flight is provided, wherein the method comprises the steps of: permitting access to a computer software application; enabling a proposing user to propose a flight itinerary to be shared with searching users, said proposed flight itinerary having associated therewith a plurality of flight parameters, wherein one of the plurality of flight parameters is the pro posed departure time of day, and wherein said proposed departure time of day further must not be expressed as an exact numerical value; associating said proposed flight itin erary with the proposing user that proposed said flight itiner ary and uniquely identifying and storing said proposed flight itinerary and associated plurality of flight parameters in a computer searchable database associated with said Software application, said database storing a plurality of proposed flight itineraries, each having associated flight parameters; enabling a searching user to enter at least one of a plurality of search parameters and searching said database for proposed flight itineraries having associated flight parameters that match at least Some of said search parameters; displaying to said searching user all proposed flight itineraries having at least some matching flight parameters; enabling said search ing user to directly access one or more of said matching proposed flight itineraries to directly negotiate with one or more of said proposing users that have proposed said dis played matching flight itineraries; whereby at the beginning of said negotiation requiring the entry of a numerical value for a specific desired departure time of day by said searching user to in order to negotiate a shared flight itinerary; and enabling the negotiation of one or more of said plurality of flight parameters of said proposed flight itinerary directly between said searching user and said proposing user and storing updated flight parameters in said database, whereby an agree ment between said searching user and said proposing user with respect to all of said plurality of said proposed flight parameters causes that proposed flight itinerary to become a common shared flight itinerary. In accordance with another aspect of the present invention, a method for allowing users to directly book a shared flight itinerary for an on-demand charter flight is provided, in which the method comprises the steps of permitting access to a computer Software application providing user accessible flight itineraries; enabling a plurality of users to negotiate directly with each other one or more of a plurality of flight parameters associated with a particular proposed flight itin erary, wherein an agreement between some or all of said users causes said proposed flight itinerary to become a shared flight itinerary; transmitting said flight parameters of said shared flight itinerary to a charter brokerage service for chartering an aircraft for said shared flight itinerary. In accordance with yet another aspect of the present inven tion, a computer-based system for negotiating shared flight itineraries for on-demand charter flights is provided, in which the system comprises: a first computer, executing at least a part of a Software application for negotiating shared flight itineraries; a data storage device coupled to said first com puter, comprising a computer-searchable database; a second computer, having a display and an input device, and capable of accessing said first computer via the Internet and further capable of executing at least a part of said Software applica tion for: a) enabling proposing users to propose flight itiner aries to be shared with searching users, each of said proposed flight itineraries having associated a plurality of flight param eters, wherein one of the plurality of flight parameters is the proposed departure time of day, and wherein said proposed departure time of day further must not be expressed as an exact numerical value; whereby said software application associates said proposed flight itinerary with the proposing user that proposed said flight itinerary and uniquely identifies and stores said proposed flight itinerary and associated plu rality of flight parameters in said computer searchable data base; b) enabling searching users to enter at least one of a plurality of search flight parameters to search said database for proposed flight itineraries having associated flight param eters that match at least some of said search flight parameters; c) displaying matching proposed flight itineraries; d) enabling said searching user to directly access one or more of said matching proposed flight itineraries to directly negotiate with one or more of said proposing users that have proposed said displayed matching flight itineraries, whereby at the beginning of said negotiation said searching user must pro

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT The disclosed invention provides for a system and method that enables users with similar or matching travel plans to find each other and to directly negotiate with each other a single flight itinerary utilizing a charter aircraft to be shared among them. The disclosed invention further provides for a system and method that enables the users that have successfully negotiated a shared flight itinerary to then directly book the shared flight itinerary, whereby an air charter brokerage ser vice will provide a charter aircraft for the booked shared flight itinerary. The preferred embodiment of the disclosed invention is a web-based negotiation software application, accessible to registered users via the Internet using a personal computing device and a web browser. The software application may be maintained and hosted by an air charter brokerage service. Users who wish to access the software application via the Internet may be required to register as members of the air charter brokerage service. As part of the registration process, users may be asked to provide certain identifying informa tion, Such as name and address, as well as billing information, Such as a credit card number. Once users have enrolled as members, they will be asked to set up a username and a password that will allow them to Subsequently access the web-based negotiation Software application. 1. Negotiating a Shared Flight Itinerary In order to negotiate a shared flight itinerary, in the pre ferred embodiment, a user, i.e., member, must first access the web-based negotiation software application by entering the correct username and password. After gaining access to the application, the user is presented with a user interface Such as the one depicted in FIG. 1. FIG. 1 depicts one embodiment of a user interface home screen 100 which presents the user with a number of menus that enable a user to, for example, search for proposed flight itineraries using search open flight pro posal menu 110, directly book a flight by using book a flight menu 130, propose a desired flight itinerary by using propose a flight menu 120, and generate a quote for the cost of a particular flight itinerary using cost calculator 140. In addition, home screen 100 may also display the user's open flight proposals in open flight proposals menu 151 and the user's closed flight proposals in closed flight proposals menu 152, if applicable. Furthermore, home screen 100 may also display the user's open invitations to book a shared flight itinerary in open flight invites menu 153, the user's booked flight itineraries in booked flight invites menu 154, c) the user's expired flight

15 7 invites inexpired flight invites menu 155, and the user's failed flight invites in failed flight invites menu 156. Users of the disclosed negotiation Software application will have at least two objectives in common: they, 1) enjoy the flexibility and comfort of traveling with a private aircraft, but 2) would like to minimize the associated expenses of on demand aircraft charter by sharing the flight itinerary with as many other users as possible. In a typical scenario, every user will have in mind a specific desired flight itinerary, but will also be willing to negotiate certain details of the itinerary with other users in order to negotiate a single common flight itin erary to be shared by a plurality of users. For example, Member A, living in Omaha, needs to be in New York City by noon of Nov.30, Ideally, Member A would like to leave Omaha in the morning of Nov.30, Member A would also like to share the expense of chartering a private aircraft for the trip from Omaha to New York City and is looking for other users, i.e., members with whom to share a common flight itinerary. a. Starting a New Negotiation The Initial Flight Proposal Before members are able to negotiate a shared flight itin erary with each other, at least some members must provide initial flight proposals. Members proposing flight itineraries are hereinafter referred to as proposing member(s)' and members searching for open proposed flight itineraries are hereinafter referred to as searching member(s). FIG. 2A provides an overview of the steps that comprise the creation of an initial flight proposal, i.e., a proposed flight itinerary, which is more fully explained below and shown in FIG. 2B. In a first step 601 a proposing member enters an initial flight proposal by entering certain initial flight param eters. In an optional second step 602, the member can request a quote based on the entered flight parameters, which is calculated and displayed to the requesting member in optional step three 603. In a fourth step 604 the initial flight proposal Submitted and saved in a searchable database as an open flight proposal. FIGS. 2B through 2C show a preferred embodiment of a user interface, in particular, initial flight proposal interface 200 which enables a member to propose an initial flight itinerary and to request a quote based on the entered flight parameters. In the example shown in FIGS. 2B and 2C, pro posing Member B 201 has entered initial flight proposal inter face 200 after having selected the propose a flight menu 120 on home screen 100 as shown in FIG. 1. The initial flight proposal interface 200 allows proposing Member B 201 to enter certain flight parameters (or flight terms) that make up the proposing members initial flight proposal. As such, a proposing member enters at least a departure location in departure location menu 202 and a destination location in destination location menu 203. In the example shown in FIG. 2B, proposing Member B 201 has entered Omaha as the departure location and New York City as the destination loca tion. Furthermore, a proposing member also enters a depar ture date in departure date menu 204 and a departure time frame in departure time menu 205, such as, for example, morning, noon. afternoon or evening. The disclosed negotiation Software application does not allow proposing members to enter an exact departure time, since proposing an exact numerical time indication, such as, for example, 6:35 PM or 18:35, could be interpreted as a specific, i.e., "scheduled departure time As mentioned above, current FAA regulations do not allow on-demand aircraft charter services to post scheduled flights, whereby a scheduled flight is defined as having a departure location, a destination location and a specific depar ture time. However, and as will be further explained below, once a searching member has entered the negotiation, all flight parameters of an open proposed flight itinerary, includ ing a specific numerical departure time, are available for negotiation. The preferred embodiment of FIG. 2B provides for a pro posing member to define additional flight parameters of a proposed flight itinerary. A proposing member can indicate whether the proposed flight itinerary is to be a one way trip or a round trip by making the applicable selection in one way/ round trip selector 206. In addition, the size of the desired charter aircraft or the maximum number of available passen ger seats can be indicated in aircraft size selector 207. The number of passengers associated with the proposing member can be entered in unavailable seats indicator 208 and the number of seats that the proposing member is willing to share with other members can be entered in available seats indicator 209. Furthermore, the preferred embodiment of FIG.2B pro vides for a proposing member to identify the lead passenger of the proposed flight itinerary in lead passenger menu 210. The type of travel, for example, business or personal can be selected in type of travel selector 211. Whether the pro posing member is planning to take along children or pets, or whether children or pets are welcome, can be indicated in child policy selector 212 and pet policy selector 213, respec tively. A proposing member can also indicate by what date the negotiation must be finished in close negotiation date menu 214. After the selected date the proposed flight itinerary will no longer be available to searching members. A proposing member may also provide a range of possible departure dates in departure date range menu 215 indicating greater flexibil ity as to the departure date. In this Example, Member B has entered the departure location Omaha', the destination location New York, a desired departure date of November 30, an alternative desired departure date of November 29, and a desired departure time frame of morning. Furthermore, proposing Member B indicated that the proposed itinerary is for a one way flight only, that the proposed charter aircraft size is light with a maximum of 6 passenger seats, whereby pro posing Member B will occupy 2 seats, leaving 4 seats to be shared with other members. Finally, proposing Member B identified Member Bas the lead passenger, and indicated that the proposed trip will be personal in nature, and children and/or pets are welcome. The negotiation must be closed by November 27. After a proposing member has entered all required initial flight parameters in initial flight proposal interface 200, the entered initial flight parameters will be uniquely associated with the proposing member and stored in an accessible and searchable database associated with the air charter brokerage service so that other searching members can find the open proposed flight itineraries. In the preferred embodiment of FIG. 2B, selecting submit flight proposal 216 causes the disclosed negotiation Software application to uniquely asso ciate and identify said flight parameters as Member Bs 201 proposed flight itinerary and to save said flight itinerary in an accessible and searchable database. In addition, the preferred embodiment as shown in FIG.2B allows a proposing member to request a quote for the pro posed flight itinerary based on the entered flight parameters. In particular, selecting get quote 217 causes the disclosed

16 negotiation Software application to calculate the estimated cost of the flight itinerary based on entered flight parameters. FIG. 2C shows a preferred embodiment of an estimated cost display screen 220 that is part of the cost calculator 140 shown in FIG. 1. In particular, estimated cost display Screen 220 may display, among other information, the total esti mated cost 221 and the estimated share 222 of the cost attrib utable to the member requesting the quote. The disclosed negotiation Software application permits a plurality of proposing members to enter end Submit initial flight proposals to be stored in the accessible and searchable database. The larger the pool of proposing and searching members, the more likely participating members will be able to Successfully negotiate shared flight itineraries. b. Searching Open Flight Itineraries Typically, a member entering the negotiation application will first want to search for open flight proposals submitted by proposing members, whereby the objective is to find pro posed flight itineraries that have matching or at least similar flight parameters compared to those of the searching mem ber's own desired flight parameters. FIG. 3A provides an overview of the steps that comprise the search for an open flight proposal, i.e., a proposed flight itinerary, which is more fully explained below and shown in FIGS. 3B and 3C. In a first step 605 a searching member enters the desired flight parameters. In a second step 606, the searching member Submits the entered desired flight param eters. Next, in a third step 607, the disclosed negotiation Software application searches the associated database of pro posed flight itineraries for those proposed flight itineraries that have either matching or similar flight parameters. Finally, in a fourth step 608 the application displays to the searching member the search results, i.e., all matching or similar pro posed flight itineraries. FIGS. 3B through 3C show a preferred embodiment of a user interface, in particular, search flight proposal interface 300 which enables a searching member to search for open flight proposals (or open negotiations ) that have flight parameters that are matching or are similar to the searching member's desired flight parameters. In the example shown in FIG. 3B, searching Member A309 has entered search flight proposal interface 300 after having selected search open flight proposal menu 110 on home screen 100 as shown in FIG. 1. The search flight proposal interface 300 allows searching Member A 309 to enter certain flight parameters (or flight terms) that make up the searching member's desired flight itinerary. As such, a searching member may enter desired flight parameters such as, for example, a desired departure location in departure location search menu 3.01 and desired destination location in destination location search menu Furthermore, a searching member may also select to con duct an advanced search by selecting advanced search selec tor 303 to further define the search for a proposed flight itinerary, by selecting a certain desired departure date range 304, the desired type of travel 305, i.e., personal or business, and the desired policy regarding the transport of children and pets, in desired children policy selector 306 and desired pet policy selector 307. After all desired flight parameters have been entered using search flight proposal interface 300, selecting search 308 causes the disclosed negotiation Soft ware application to start the search of its associated database for open flight proposals with matching or similar flight parameters. In order to have the disclosed negotiation soft ware application to display all open proposed flight itineraries that are stored in the associated database at the time a search ing member conducts the search, the searching member sim ply selects search 308 without entering any desired flight parameters. Of course, the more desired flight parameters are entered the narrower the search results. In the example shown in FIG. 3B, Member A 309 has entered Omaha' as the desired departure location, New York City as the desired arrival location, a desired departure date range of between November 30 and November 29, and indicated that the desired type of travel is personal and that children and pets are welcome. FIG. 3C shows a preferred embodiment of a user interface, in particular a portion of search flight proposal interface 300, i.e., destination search result menu 310. In this example, the disclosed negotiation Software application, in response to searching Member A selecting search 308, has retrieved all proposed flight itineraries that match or are similar to search ing Member A's desired flight parameters. In this example, the disclosed application displays the open flight itinerary of Member B. By selecting enter negotiation 311, searching Member A can access Member B's proposed flight itinerary to directly negotiate all flight parameters of the proposed flight itinerary. Should the search fail to produce any pro posed flight itineraries Suitable to the searching member, the searching member may enter a new flight proposal by select ing propose new flight itinerary 312, which will open up a new initial flight proposal interface 200 as shown in FIG. 2B and the searching member becomes a proposing member, whereby the steps explained with regards to FIGS. 2A through 2C may be repeated. c. Negotiating a Shared Flight Itinerary FIG. 4A provides an overview of the steps that comprise the negotiation of a shared flight itinerary which is more fully explained below and shown in FIGS. 4B through 4.J. In a first step 609 a member enters an open flight itinerary, i.e. open flight proposal. In a second step 610 the member enters or updates certain flight parameters. However, the first member entering the negotiation of an open flight proposal must input at least a specific departure time, for example, 9 AM instead of a departure time frame Such as "morning. In an optional third step 611, the member can request a quote based on the entered/updated flight parameters, which is calculated and displayed to the requesting member in an optional fourth step 612. In a fifth step 613 the entered/updated flight parameters of the open flight proposal are Submitted and saved in a searchable database. In a sixth step 614, all members partici pating in the open flight proposal are notified of the entered/ updated flight parameters. In a seventh step 615, the negoti ating members may or may not have reached agreement on all flight parameters. If all negotiating members have reached agreement, they are allowed to book the shared flight itinerary in an eighth step 616. If the negotiating members have not reached agreement on all flight parameters, they may, in a ninth step 617, continue to submit updated flight parameters until agreement has been reached, or some or all negotiating members may decide to discontinue the negotiation. FIG. 4B shows a preferred embodiment of a user interface, in particular, flight proposal detail menu 400 which enables a searching member to enter a selected open flight proposal to directly negotiate its flight parameters with the proposing member. In this example, flight proposal detail menu 400 was accessed by searching Member A 412 by selecting enter negotiation 311 on destination search result menu 310 as shown in FIG.3C. Flight proposal detail menu 400 provides the searching member with all proposed flight parameters entered by the proposing member, Such as, for example, pro

17 11 posing member's name 401, the estimated cost 402, aircraft size 403, proposed departure location 404, proposed destina tion location 405, proposed departure date 406 and proposed departure time frame 407. The type of travel 408 and children 409 and pet policies 410 are also indicated and may be shown in form of icons corresponding to icon key 411. In this example, searching Member A 412 can now directly contact proposing Member B 401 by selecting enter flight proposal 413 to start the negotiation of proposing Member B's open flight itinerary. FIG.4C shows a preferred embodiment of start negotiation interface 420, which allows a searching member to start the negotiation of the selected open flight proposal. This start negotiation interface 420 is largely identical to the initial flight proposal interface 200 shown in FIG. 2B but for one critical difference regarding the specificity of the required departure time parameter. Unlike initial flight proposal inter face 200 of FIG.2B that did not allow a proposing member to enter a specific numerical time indication in departure time menu 205 for the reasons explained above, start negotiation interface 420, shown in FIG. 4C, now requires that the first searching member to enter or start the negotiation of the selected open flight proposal must enter a specific numerical time indication in departure time menu 421 of start negotia tion interface 420. Furthermore, the number of passengers associated with the searching member can be entered in pas senger number indicator 422 and the number of seats that the searching member is willing to share with additional search ing members can be entered in available seats indicator 423. Furthermore, the lead passenger of the searching members travel party can be identified in lead passenger menu 424. The type of travel can be selected or confirmed in type of travel selector 425. Whether the searching member is planning to take along children or pets, or whether children or pets are welcome, may be indicated in children policy selector 426 and pet policy selector 427, respectively. A searching member can also indicate by what date the negotiation must be fin ished in close negotiation date menu 428. In addition, the preferred embodiment of start negotiation interface 420 as shown in FIG. 4C allows a searching member to request a quote for the flight itinerary being negotiated based on the flight parameters entered at the time of the quote request. In particular, selecting get quote 429 causes the dis closed negotiation Software application to calculate the esti mated cost of the flight itinerary based on entered flight parameters FIG. 4D shoes a preferred embodiment of an estimated cost display screen 440 that is part of the cost calculator 140 shown in FIG. 1. In particular, estimated cost display Screen 440 may display, among other information, the total esti mated cost 441 and the estimated share 442 of the cost attrib utable to the member requesting the quote. In this example, illustrated in FIG. 4C, searching Member A 431 has entered 9 AM in departure time menu 421 in accordance with Member A's desired departure time. Mem ber A 431 also indicated the need for 2 seats in passenger number indicator 422. In the preferred embodiment of FIG. 4C, selecting submit flight proposal 430 causes the disclosed negotiation Software application to update the database with the entered flight parameters and to also notify all other mem bers participating in the negotiation of the recently updated flight parameters. Such notification may be via electronic message to participating members and is generated every time the proposed flight itinerary is updated. The software application further has the ability to generate a notification to all searching members whose desired destination location is identical to a proposing members proposed destination loca tion, as soon as the proposing member has proposed, i.e., Submitted Such destination location to the application's data base. FIG. 4E shows a preferred embodiment of negotiation interface 450 allowing a negotiating member to further update the flight parameters of the proposed flight itinerary being negotiated after the negotiation has been initiated. Negotiation interface also allows a member to monitor the negotiation activity of other members. After every update of flight parameters, a member must select update terms 451, in order to cause the disclosed negotiation software application to update its associated database of proposed flight itineraries. Furthermore, members are able to leave the ongoing negotia tion at any time before the proposed flight itinerary has become a shared flight itinerary by selecting drop out 452. FIG. 4F shows a preferred embodiment of a portion of negotiation interface 450, i.e., all members list 453, which lists all members currently participating in the negotiation. This list is constantly updated by the disclosed negotiation software application. In this example, all member list 453 lists only Member A and Member Bas negotiating a flight itiner ary between Omaha and New York City and in particular, that Member B has proposed to depart Omaha for New York City at 11 AM on Nov.30, 2009, whereas Member A has proposed a departure time of 9 AM on Nov.30, FIG. 4G shows a preferred embodiment of a portion of negotiation interface 450, i.e., matching members list 454a, which lists all members that have matching or similar flight parameters. Matching member list 454a also includes an indication of how similar the respective flight parameters are. In this example, the matching members list 454a displayed as part of Member A's 443 negotiation interface 450 indicates through match indicator 455a that at this time Member B's proposed flight parameters are a 75% match to Member As proposed flight parameters. There is not a 100% match in this example because Member A and Member B have not yet agreed on a common departure time, since Member A has proposed 9 AM and Member B has proposed 11 AM. FIG. 4H shows a preferred embodiment of a portion of negotiation interface 450, i.e., member activity 456, which tracks the negotiation activity of all members participating in the negotiation of the flight itinerary. In this example, member activity 456 shows the creation of Member As and Member B s proposals, and also shows in the last entry that Member B has updated the proposed departure date from 11 AM to 9 AM. This update by Member B has now generated a 100% match between the flight parameters of Member A and Mem ber B as indicated in matching members list 454b, and in particular by match indicator 455b as shown in FIG. 4I. FIG. 4J shows a preferred embodiment of a portion of negotiation interface 450, i.e., my matches 457, which lists all members whose proposed flight parameters are identical, i.e., a 100% match. In this example, after Member B had updated the departure time from 11 AM to 9 AM, my matches 457 now lists Member B as having 100% matching flight parameters compared with Member A's flight parameters, that is, both Member A and Member B have agreed to depart Omaha for New York City on Nov. 11, 2009 at 9 AM. Member A now has the option to invite Member B to book the now common shared flight itinerary by selecting invite to book 458. The software application further has the ability to generate a notification to all searching members whose desired desti nation location is identical to a proposing members proposed destination location, as soon as the proposing member has proposed, i.e., Submitted Such destination location to the application's database. Such notification may beinform of an electronic message send to participating members.

18 13 2. Booking a Shared Flight Itinerary While one aspect of the disclosed invention is to enable searching members and proposing members to directly nego tiate a shared flight itinerary, Such negotiation occurs prior to and independent of the booking and chartering of an aircraft that will carry out the shared itinerary. Therefore, another aspect of the disclosed invention is the ability of users to directly book a Successfully negotiated shared flight itinerary. More particularly, once members have Successfully nego tiated all flight parameters of a particular proposed flight itinerary, i.e., once all flight parameters are a 100% match, any of the participating negotiating members can invite the other negotiating members to book the negotiated flight itin erary. For example, and as explained above, FIG. 4J shows a preferred embodiment of a portion of negotiation interface 450, i.e., my matches 457, which lists all members whose proposed flight parameters are identical, i.e., a 100% match. In this example, Member A now has the option to invite Member B to book the shared flight itinerary by selecting invite to book 458. In another embodiment, the disclosed application may automatically invite all members with 100% matching flight parameters to book the shared flight itinerary. FIGS.5A and 5B show a preferred embodiment of a book ing interface 500 that allows members to manage their book ing invitation. In this particular example, booking interface 500 displays all members that have been invited to book a particular shared flight itinerary. In this example, booking interface 500 shows some basic flight parameters of the shared itinerary, such as departure location 501, destination location 502, departure date 503, departure time 504, the passenger total 505, the total flight cost 506, Member A507 and Member B508 and their respective flight cost share 509 and their respective booking status 510. In the preferred embodiment, each member can choose from a menu of pre pared status messages available in status message menu 511, such as, for example, Yes, ready to book, or No, not ready to book or similar status messages. After every status update a member must select update 512, causing the disclosed nego tiation Software application to update its associated database. Once a member indicated the willingness to book the flight, the member will be prompted to enter payment information, Such as, for example, the members credit card information. An example of a billing interface 513 is shown in FIG. 5B. In order for the shared flight itinerary to become a booked flight, all invited members must expressly agree to book the shared flight itinerary. If any one of the users does not agree to book the shared flight itinerary, the invitation to book this particular shared flight itinerary expires or closes and no flight itinerary is booked. FIG. 5C shows an example of a booking status interface 520 where a member has confirmed the willingness to book the shared flight itinerary and has provided the required pay ment information. In this example, not all members partici pating in the shared flight itinerary have confirmed the will ingness to book the shareditinerary and therefore the status of the invitation is indicated as Open. Once all members have accepted the invitation to book the shared flight itinerary, the members will be charged their share of the cost using the member's submitted payment information. At this point the proposed shared itinerary becomes a scheduled itinerary. Once a shared itinerary has been booked, i.e., scheduled, it will no longer be available to other users of the disclosed software application. The booked itinerary will only be acces sible to the members who negotiated the particular shared flight itinerary, but will not be included in search results of other searching members Finally, (not shown) the disclosed application forwards the details of the shared flight itinerary to the associated air char ter brokerage service, where the flight parameters of the shared flight itinerary are used to charter an aircraft to fulfill the shared itinerary. The foregoing description of the invention has been pre sented for purposes of illustration and description, and is not intended to be exhaustive or to limit the invention to the precise form disclosed.
